Number of envelopes is equal to 2^n, where n obtained by
reading 2 bits from bit stream,so maximum value for number
of envelopes is 8. Time slot array table is accessed using
number of envelopes. The Minimum and Maximum values are 0
and 6,based on these values the table is modified.

Maximum crc registers allowed is 7. Crc registers are accessed
and updated inside the function ixheaacd_adts_crc_start_reg().
Check has been added before the function call so that if the
register value is less than 7 then only the function gets called.

Reason for crash:
For the below reported issues input stream has only one
coupling channel element. As per the specification coupling
channel element should be associated with at least one main
channel element.
We have different output buffers for main channel
and coupling channel. In this error case the coupling
channel output buffer is not getting updated because
there is no main channel, so main decode is called with
output buffer pointing to NULL.
This is the reason for all the issues listed below.

Number of elements allowed in usac profile are 16. Erroneous input
stream in this use case has 63336 elements.We have an error
check for this max number of elements while parsing the decoder
configuration.This returned error code was not handled properly.
Maximum 16 config elements can be used while codec creation,because
of number of elements values is coming as 63336, during
creation time OOB read is happening.

While parsing the input stream in mps_pre_matrix function,
there was an error.This error was not handled properly,
because of which further values which are read from bit stream
are getting wrong values.
We use these value in iteration in ixheaacd_mps_getstridemap()
which is causing stack-buffer-overflow

(cherry picked from commit 28a1411d72)
The maximum number of channels supported for usac profile in
libxaac decoder is two only.Input streams of the below reported
issues contain multi channel,because of multi channel the write
offset is incremented by greater 2, which causes out of bound
memory access while writing.
